“The Automaton” is my take on how to do a low budget robot controller.
Tech specs 6 - 45V input voltage range. Support for up to 32 servos with a maximum total current draw of 6A at 5V. 24Hz to 1526Hz PWM controller with 12 bit resolution. 240MHz MCU with WiFi and Bluetooth. 9DOF sensor fusion IMU that outputs absolute orientation angle at 100Hz. FTDI programming header. Expansion header with 14 available GPIO pins.
During a family trip to Japan last easter, I was fortunate enough to have a couple of hours to myself in the tech mecca of Tokyo, namely the Akihabara district.
My two hour “geek pilgrimage” involved plans for visiting four of the more iconic shops in Akihabara. These were Mak Japan, G-Front, Tsukomo Robot Kingdom and Vstone Robot Center.
After having spent quite some time looking at maps and web sites, I was finally able to locate the entrance of the MAK Japan shop.
Inspired by the last local robot tournamet at Omega, the Norwegian initiative Lær Kidsa Koding and a few discussions at my local hackerspace (Hackhem) I decided to revisit the BBC Micro:bit platform to see if it would be suitable as a mini sumo controller.
The idea was that it would be really cool to attempt a design of an entry level mini sumo platform, that used commonly available parts, didn’t cost an arm and a leg, was easy to build and easy to program.
After having wanted to get into kit making for some time, I finaly decided to give it a go. This year, I had a few Nixie clocks on display at Trondheim Maker Faire, and later also at Oslo Skaperfestival. The clocks generated enough interest to justify a limited run of kits.
I am now offering a Nixie Clock kit in two versions.
A “Full kit” version that contains all necessary parts for the clock.
Norwegian Spar 7 machine.
You will probably want one of these… Spar 7 replacement boards.
I made a new batch of these a few days ago. Initially I thought that I had lost the gerber files and the Target 3001 design files, but I was fortunately able to locate them in one of my old backups.
If the files had been lost, I could easily have redesigned these boards, using SMT components in order to make them even more compact.
